d is your answer; I hope this assists you.
Answer:
are present in solution.
Explanation:
Molarity of the solution = 0.210 M
Volume of the solution = 65.5 ml = 0.0655 L
Moles of aluminum iodide = n
n = 0.013755 moles of aluminum iodide
Each mole of aluminum iodide yields 3 moles of iodide ions:
Thus, 0.013755 moles of aluminum iodide will provide:
moles of iodide ions
The total number of iodide ions in 0.041265 moles:
are present in solution.
a) 101%, b) 59.7%.The thermal decomposition of baking soda is represented by the equation: 2NaHCO3 → Na2CO3 + H2O + CO2. The calculation of moles from 1.555g of baking soda yields approximately 0.0185 moles. Utilizing the stoichiometry of the reaction, the theoretical yield is determined, and the percent yield is found to be 101%. Similarly, an unknown mixture of baking soda decomposing shows a percentage of NaHCO3 as 59.7%.
In alkenes, the existence of cis and trans isomers arises due to the inflexible double bond which inhibits rotation, having groups attached to the double bond's carbon atoms that remain static in relation to each other, thus leading to varying geometries; these are two distinct molecules with slightly differing characteristics.
-Trans indicates the ends of the chain are opposite each other around the double bond.
When naming Cis-Trans isomers, the terms cis or trans are prefixed to the name of the alkene when such isomers exist.
